To all whom tt may concern:

Be it known that we, THOMAS COLLINS and ERNEST LOUIS HARTMANN, citizens of the United States, residing at Bainbridge, in the county of Chenango and State of New York, have invented an Improvement in Gentrifugal Liquid-separators, of which the following is a specification.

Our invention relates Vto improvements in centrifugal liquid separators, and the same is an improvement upon the device shown and described in Letters Patent of the United States,A granted to us August l, 1905, #796,189 and #796,190.

In the devicevofour said patents, the cream tube is secured to the upper annulus disk of the inner member and its free upper end entersa hole in the cover adjacent to the adjustable plug of the cream discharge. We have discovered difficulties in the operation of this device to the extent that occasionally the blue or skim milk would discharge through the cream Orifice coming up the outer surface of the cream tube from the upper surface of the annulus disk to which it was secured3and also that the entire cream out-put was not dischargedI as was manifest in washing put the separator, because a small amount of cream would precede the washing l character and in a separator for other liquid, receives and conveys away the liquid of lightest specific gravity.

In the drawing, Figure lis a vertical section and partial elevation representing the device of our invention at the upper end of the centrifugal liquid separator,

' and Fig. 2 is a sectional plan above the top disk of the inner member.

l Generally speaking, the 1c`onstruction of our improved centrifugal separator is the same as shown in our before mentioned patents, and therefore we. have only shown .the upper part of the"device to which our present invention peculiarly relates.

The bowl-a is preferably cylindrical and is revolved at a high speed. A cover b is provided for the bowl and .granted tous,` August l, 1905,'No. 796,1891.

We have shown and prefer 'to increase the thickness of the cover near the central aperture at the upper end of which is an adjustable plug b2, for thel'cream discharge seated in a cream discharge aperture, which extends through the cover. sired character and it is adapted to beturned so as to bring -the opening therein either nearer to or further and setting upon a rubber or other suitable gasket?? This plug may be of any de' In theupper end of the bolt c, near 'the lower'end of y the tubular portion,v we provide tube sections 3 for the discharge of the orother liquid admitted .into thetubular end -of the bolt, the same passing' through these-openings'into the centrifugal separator.

ting snugly down into thebowl; this liner comprising several vertical radial' bars e and a series of superim-` posed or nested annulus plates f set Obliquely to ver` tical lines, or in other words, each formed `as conio '475' As in our aforesaid patents, we vprovide a lineriit- Y so? sections. The inner member fitting within the liner' comprises as a part thereof an annulus disk h at the liquely across radial lines from the center of the bowl and .are preferably placed vertical., The top annulus disk it is provided with perforations 4 preferably spaced apart so that there is one between each of the respective4 blades i; the said p'erorations 4 being preferably arranged on an arc which advantageously intersects the blades 't'. i

The liquid isdelivered into the centrifugal separator through the tubular upper end of the bolt and" top and blades i, which cross-section are set Ob# through the tube sections .3 and'passes to the upper surface of the annulus disk h and through the perforations 4 to the nested annulus plates f below. In this lannulus disk h there is a perforation 5 of liberal proportions to receive the cream tube c.. This tube is preferably constructed similarly to the tube of our aforesaid'patents, it passes freely through the perforation of the annulus disk h and is lat its upper end secured to and sealed in the cream discharge openl of the cover so thatonly the liquid which s through the tube may be discharged through the ad justable plug b2. The clearance thus provided tween the exterior oi the tube 1c and thesurface I of the annulus, disk h acts to prevent any liq'ind that lienon top of this annulus disk .congregating on `4the.exterior oi the tube k and performing any function vvin so doing..J

Where thewdevice is used for the separation of milk irornlits cream, the blue milk orskim milk which would lie upon the top of the lannulus disk -h cannot any function or in any way act to the-detrinient of th action ofthe separator if it-also collects on the outsideof the cream tube Ic, as the solid connecof the separator rises, it finds its natural discharge tion of ltleupier part of the tube t the cover effec- -tually prevents any discharge through the plug b2 of anything except the material that passes directly through the tube 1:, and as the cream from the interior through the fuse Laird the adjustable p1ug b2. Where tube k. y

The tube k or cream tube, is a conduit of any suit- .ablve or desired material or character, and .where the centrifugal separator is not employed for the separa:-

i tion of the cream trom the sknl or blue milk, but for the separation of. the partsof other liquids, the said tube k serves as a conduit for conveyingv away the liquid of lightest specific gravity.

We claim as our invention: A

1; In a 'centrifugal liquid separator, the combination with a bowl and liner, of a cover having`a discharge ori- ICe, a conduit for the liquid of lightest gravity, one end of which is securely fastened therein and sealed thereto, and a. disk extending over th'e linerV and having an openingthrough which 4the said tube freely passes down' into the bowl.

2. In a centrifugal liquid separator, -the combination' with a bowl and liner, of a coverv having a. dischargev orifice and n conduit for the liquid of lightest gravity secured only at one end tothe c over inthe said discharge,

'oriice, vand so made liquid tight, substantially as described. A

'3. In a .centrifugal-liquid separator, the combination with a' bowl and liner,'of a cover havingwu cream discharge orifice, a creamconduit, one end of which enters and is securely fastened therein and sealed thereto, and a disk extending over the liner and forming a partei.' an .inner member and having perforations for the down discharge of the milk and an opening through which the cream tube' freelyv passes down into the bowl.

' Signedy by us this 24th day of Sept., 1906.
